Hey guys I`m going to need a quick response here, I have a 20g aquarium that is half full, around 10g of water and I want to make it .002 brackish, how much marine salt should I add? I have all that I need I just need the amount.

Sorry guys I tried to search but I couldn`t really find the exact amount needed.


Thanks!

use your Hydrometer, Bud

About 1/4 cup per 5 gallons will get you 1.0025 sg brackish water. This is barely brackish water at all and is pretty much fresh water.

What sg are the crabs supposed to be in?

Btw, I used to keep my silver dollars, which are freshwater fish, in 1.005 for nearly a year. They were absolutely fine in it.

I'm in the process of doing a brackish Moray/Cichlid community myself :)
 
That's an interesting brackish tank. Are there any cichlids that are actually brackish or are you just going to acclimate them very slowly?

Geophagus brasiliensis , Paraneetroplus maculicauda and Mayaheros uropthalmus have been found several miles out to sea. Lab studies with Rocia octofasciata, Herichthys cyannoguttatum showed that not only did they survive in Brackish conditions, but actually did BETTER than in pure Fresh water.....personally I found the rate of acclimation to be quite radical and a only a mere 2-3 days in between increasing salinity. Same study was done to Amphilophus labiatus with poor results. duanes duanes , I know you can add to this
 
Etroplus suratensus (green chromides) are usually considered brackish as adults.
The thing about Mayaheros uropthalmus is there are many location variants, some evolved to live in fresh, some brackish, and some pure sea water. And at some point some may end up being considered separate species, so plopping a fresh water variant in salty water without a lengthy break in period could be counter productive, and produce stress, or any cichlid for that matter.
If you are going to really do brackish, getting a proper hydrometer, or salinity meter, would be the fist thing to do. Just trying to measure a cup here or a half pint there, and guess about salinity could become problematic later of when trying to adjust water changes.

Its okay I found a calculator online and Its a good thing I did because nobody gave me a useful answer.

I know that its not a high salinity, I didn't want to kill my established bacteria so I will slowly raise it over time. It was a very simple question.

Filament barbs are brackish water fish too I have 7 of them in my 120 and they are beautiful. They are also in freshwater, I would recommend them to anyone who wants a colorful shoaler for the brackish aquarium (there are not many)

Either way my crab has a very nice set up and hes settling in well and will get some tankmates when he has settled more.

sticking to the off topic theme of this thread are there any smaller cichlids capable of low end brackish conversion? Dwarf cichlids or something. I`m guessing that because most come from soft acidic water that they are few and far between

NOT USEFUL??? I think there was only ONE answer to that question, and anything else is null and void.

Buy a Hydrometer. I got one last week.
